pplication filed April 12, 1916. Serial No. 90,717.

To all whom t m ag/ concern: l

Be it kno-Wn that l, Cuantas L. Besten, a citizen of the United States,residing at Winfield, in the county oit Cowley and State of Kansas, haveinvented certain new and useful improvements in 1Weter-lR-egulators forEnginodtadiators; and l' do hereby declare the following to be a full,clear, and exact description oi the invention, such as willenableothers' skilled in the art to which it appertains to make and usethe same.

This invention relates to the Water-cooling of internal combustionengines, especially those of automobiles; and the object of theinvention is to provide for the maintenance of a uniform water-level inthe radiator at all times. c

The invention has been devised tor use more particularly in connectionWith Water regulating apparatus, for which Letters JPat- 'ent No.1,170,475 Were granted to me on the `first day of February, 1916 towhich ref erence may be had for specilic details in connection with abrief and general description following.

In the accompanying drawing, Figure l is a sectional view illustratingthe invention as applied to an automobile. Fig. 2 is a longitudinalsection of the main water regulating device as shown in the abovementioned patent. Fig. 3 is a similar vievv ot the auX- iliary oroverflow regulator which forms the subject matter o1? this application.

In the above mentioned patent the apparatus for maintaining a uniformWater-level in the radiator l is a surplus Water supply tank 2,preferably mounted under the cowl 3, at a somewhat higher level than thetop of the radiator, and feeding said radiator by gravity through themedium of a Waterregulator 'shown in Fig. 2. This comprises a smallchamber i, connecting with the supplytank by a pipe 5, and with theradiator by an outlet pipe 6. The lovv of Water through the outlet iscontrolled by a float 7 and a Water cut-oit consisting oi' a flexibletube 8 connecting with the outlet and a pinching blade 9 coperating withthe float and the base of the float support to close said tube.

In the practical use oi the device above described a. diiiculty wasencountered, arising out of the expansion and boiling ci the water inthe radiator when the engine Was very hot. This would cause the radiatorto overflow at the overlcw pipe, and thus connear the bottom of theradiator.

tinually draw Water from the surplus tank, eventually draining it. Thisdifficulty is overcome by the present invention, the overflow beingreturned to the surplus tank, and the only Waste in the Water being dueto slow evaporation, and practically negligible.

Referring now to the drawings, 10 denotes a small chamber convenientlylocated with respect tothe topot the radiator. Herein it is shown takingthe place of the usual Jfilling nozzle, the body of the chamber beingset down within the upper part of the radiator. The upper portion oi thechamber or vessel may serve as a filling nozzledLIand is provided With atightly closing cap l2. The' bottom of this nozzle (the neck foi thevessel) forms a valve-seat 13 for a valve la carried on suitable stemsl5 connecting at their lower ends With a float 16. 1When the Water inthe radiator and chamber are at the normal level the valve is closed, asshown. ,When by evaporation the Water sinks belovv the normal level thefloat sinks, opening the valve. This opens an air-vent 17, normallyclosed by the valve, and thus permits vvater from the surplus tank toenter the radiator by the action of its regulating mechanism alreadydescribed, it being understood that 'the radi- -ator 1s otherwisehermetically sealed, the

usual overflow pipe being dispensed With.

In the top of the valve la is seated a small valve'lS, Whose stem 19runs in aly guide 20 forming part of a bridge. 2l across they nozzle.The small valve islield dotvn on the larger one by a light spring 22.From the neck oi the vessel a pipe 23 runs ba'ck to the supply tank. ltwill thus be evident, that when there is an excess of Water or pressurein the radiator the surplus Water or steam Will be 'forced through thesmall valve 1 and back into the supply tank, to be there icondensed andso restored to the cooling system. l

:Owing to the agitation of the Water near the surface in the radiator,when boiling,`,the chamber containingthe Heat 16 should preferably notbe open to the Water near the top, but should be fed by a pipe 24leading to The main supply is shown as connected with this pipe, but theconnection of the supply Withthe radiator may be separate, if desired.The vent at Q5 is for the escape of Water condensing in the neck of thevessel, and to prevent freezing therein in cold Weather.

.Having thus described my invention, I claim:

1. Combined with the radiator of a combustion engine, provided with anair-vent,

t a closure for said vent actuated by the Water-level in -the radiator,and means adapted to automatically supply water to said radiator.

f l 2. Combined with a vented radiator for a combustion engine, aclosure for said vent actuated by the rising and falling of water in theradiator, an auxiliary water supply, means adapted to automaticallydeliver water therefrom to the radiator as needed, and

means coperating with the vent-closer to restore' to said water supplythe surplus Water in the radiator due to boiling or expansion.

3. Combined with a radiator and means adapted to automatically supply itwith `water at a normal level, a valve normally ed to close the radiatorhermetieally, an auxiliary, light pressure valve, a chamber therefor,and a pipe leading fi'om said. chamber to the water supply.

5. Combined with a radiator and means adapted to automatically supply itwith water at a normal level, a float-valve adapted to close theradiator hermetically, a chamber therefor, a Water connection of saidchamber with still water near the bottom of the radiator, an auxiliaryvalve opened by light pressure from inside the ra diator, a chamber forsaid valve, and a communication of said chamber with the main watersupply.

(3. Combined with a radiator and means adapted to automatically supplyit with water at a normal level, a float chamber holding water at theWater-level in the radiator, a float therein, a valve closed thereby totightly close the radiator, an auxiliary valve cooperating with thefloat valve, and opened lby light pressure from Within the radiator, achamber therefor having air and drainwents closed by the .float-valve,

and a pipe leading from the auxiliary valve chamber to the main watersupply.

In testimony whereof I affix my signature.
